T all whom 'it may concern 'devices for separating former bein the latter a so being conveyed away fromv -the interior of the machine.

,the device showing one Be it known that I, JOSHUA C. CONRAD, a citizen of the United States, and a resident of Cement, in the-county of Caddo and State of Oklahoma, have made certain new an useful Improvements in Cotton-Hullers, of which the following is a specificatiom v My, invention relates to improvements in hulls from cotton, and it consists in the combinations, constructions and arrangements' herein described and claimed.

An object of a device by means of which the cotton may be thoroughly cleaned of the hulls, the passed from the machiney and A further ob'ect of my provide a novel orm f feed mechanism for the cotton huller.

A further obje'ct of my invention is to provide a novel form of saw cylinder for separating the cotton.

,Other objects and advantages will appear in the following specification, and the novel features of the inventionvwill be particularl pointed out in the appended claims.

y invention is illustrated in theaccoinf panying drawings pl'ication, in which- 'Fi ure 1 is a face View of the device showt e driving mechanism for the' cylinders, brushes, beaters, etc., iig. 2 isa vertical section through the device, Fig. 3 is a longitudinal section through. a portion of of the. saw cylinlSiders, Fig. 4 is a fragmentary detail view of ia portion of the device,

Fig. 5 is a face view modiiied form of saw cylof a portion of a inder, and Fig. 6 is a section along the line f 6--6 of Fig. 5.

In carrying out my invention I provide a rectangular box or casing 1. At the top of this casingY and discharging into the same, is a hopper 2. The hopper is designed to be situated near, and to receive the contents of, a boll breaking and cleaninginacl'ne.

Referring now articularly to Fig. 2, it will be seen that 1n the upperv part of the casing 1 is disposed a pair of fluted spiked rollers 3 and respcctvel y, the lfoi-incr on a shaft 4 and the latter on a shaft 4.

my invention is to provide L. in Figs. l5 and 6. ,glothis -of sheet metal, such as sheet steel, is punched invention is to' with V-shape projections 13 extending outforming part of this api 5 ders 10X- Vmounted on side.

bears a series of saw disks 10 which are spaced apart by blocks `11. These blocks extendnearly to the edge of the disks, the teeth of the saw disks projecting beyond the blocks as shown in 2 Instead of making the saw cylinden n the manner shown in Fig. 3', I may .i 4in the form shown end, a cylinder 12 the direction of wardly lfand orwardly in Either of these rotation of the 'c linder. forms, z'. ef,- that s own in Fi s. 3 or 5, may be used. Between the saw cy inders and the feed rolls areV disposed brushes 14 and 14 mounted on shafts 15 and 15 respectively, while other brushes 16 and 16 on shafts 17 and 17 respectively, are disposed so as to engage the teeth -of the saw. Chutes 18 and 18 are disposed below the brushes 16 and 16 respectively. cylinders are vpicker rollers 19 and 19 on shafts 20 ,and 20 respectively. These roll-` ers are designed to pass .the hulls down the inclines 21 and 21 to the troughs 22 and 22 where the conveyers 23 and 23 ass the hulls out ofthe machine. Below t e shaft 9 on onev side of the machine, .are the shafts 9x and 9Y, each bearing saw cylinders 101l Below each of the saw posite side of the machine are the saw cylinand 101".l Brushes "16x and '16 shafts17x and 17" are disposed below the brush 16 while similar brushes 16" and 16V are disposed on the opposite The rollers-19x and 19", 19" and 19" correspond to the rollersr19` and 19 respectively. Below the beaters 5 and in alinement therewith are the beaters-.5x and 5, while similar beaters the beater 5.' Below the brushes 14 and in vertical alinement therewith are the corresponding brushes 14x and 141, each of these 5x and 5 are below v brushes being protectedv by housings 21* which form extensions of the Vchutes 21. On the other side of the devices-'are the brushes 114x. and 14". Below the beaters 74 and 7 and in alinement therewith are 4the small beaters 7"*and`v 7"" respectively. To

These rollers are operated by the gears 44 and 44 in the manner alreadypdescribed and feed the cotton downfp "tlle' beaters 5 and 5. These are revolving .nl idly and throw the cotton and the hllls se aga-inst the rapidly revolving saw cylindersl where the cotton is caught up by thefkteth. l As the cotton is carried around by thersttiiv'siA it. comes in contact'with the brushes15`andi lfwhich tends to sweep the hulls from theres cotton. The cotton is carried on aroundby the saw until it. meets the brushes'such as" those shown at 16 and 16 vwhich are revolv# ing ata high rate of speed and which, therefore, tend to 'clean the saws and to `deposit 90 the cotton on'the chutes 18 and 1S from when'` it isdelivered outside the machine.v Part; the cottonhnd the hulls Vwill fall down upon they small beatersl7 andy 7 which-1 tend to throw itonto the picker rolls 19` andy 19.

In Fig. 21 have shown three tiers of beaters, saw brushes and picker rolls corresponding to the. members 5, 7, 10, 15, 16, dhd19., Each of -theseA devices acts in precisely the same manner upon the cotton and hulls com-l ing to it as the one above it.` ltl is'obvious that the proportion offhullst'which is. carried 'out by the Ilowernriost conveyors 23' A:and
